Secretary of State Mike Pompeo then had a follow up call with the Crown Prince to reiterate the United States request for information.
"The Minister of Interior affirmed the Kingdom of Saudi Arabia's condemnation and denunciation of the false accusations circulated in some media on the Saudi government and people against the background of the disappearance of the Saudi citizen Jamal Khashoggi", an official statement had said.
Khashoggi, a wealthy former government insider who had been living in the U.S.in self-imposed exile, had written a series of columns for the Post critical of Mohammed bin Salman.
Trump's comments Wednesday were the toughest yet from his administration.
He reports that despite earlier reports to the contrary, Turkish authorities have yet to be given permission to search the Saudi consulate "in the way or with the team that they would like".
As the Times notes, officials in Turkey "have left things murky enough" by "speaking on condition of anonymity and refusing to publicly disclose their evidence", which means that much of the reporting remains unverified and the lack of concrete evidence at this point leaves room for the possibility that Khashoggi was abducted from the consulate, but not killed.
The footage from Istanbul's Atatürk Airport purportedly shows Saudi intelligence officers entering and leaving on two private jets.

Mrs Trump said she loved her husband and that the media's coverage of their relationship was not always correct. First lady Melania Trump tours Nairobi National Park, on October 5.
Turkish officials have said they believe the Saudi writer and government critic was killed inside his country's consulate in Istanbul after he visited the mission to obtain a document required to marry his Turkish fiancee.
"How is it possible for a consulate, an embassy not to have security camera systems?"
The Aljazeera correspondent Jamal Elshayyal reports from Istanbul that the investigators have heard testimony from a source who was inside the Saudi consulate at the time of Khashoggi's disappearance. He received elementary and secondary education in Saudi Arabia.
In a statement to CNN on Wednesday, a Saudi official said the kingdom "categorically" denies "any involvement in Jamal's disappearance". The Saudi government has dismissed that allegation. Saudi officials say he left shortly afterwards but Turkish officials and his fiancee, who was waiting outside, said he never came out.
The Trump administration, from the president on down, is heavily invested in the Saudi relationship. Even under the Obama administration, which had hard relations with Riyadh compared with Trump, there were some $65 billion in completed arms sales. It relies on Saudi support for its Middle East effort to counter Iranian influence and fight extremism.
The interior minister also stressed the Kingdom's keenness on the interest of its citizens at home and overseas and its keenness in particular to clarify the whole truth about the disappearance of the citizen Jamal Khashoggi.
Trump has expressed reluctance to stop selling arms, citing a $110 billion defense deal he worked out with the Kingdom as good for the economy, but told CBS' "60 Minutes" that on Sunday "We're going to get to the bottom of it and there will be severe punishment".
